Subject: Your question about the biker - Mamenchisaurus problem

to

described

is

>    Please refer to DINOSAUR TRACKS  (and other fossil footprints of the

>University Press, 1995.  On all of page 175 and continuing on page 176 (as

>world-wide, there appears to be a trend (from the earliest of Jurassic
>sauropods, through those of the Cretaceous), for the trackway gauge
>(relative positions of right and left tracks along an imaginary center
line)
>to become from literally adjacent (e.g., from the  Jurassic Purgatoire
>trackway site in Colorado) along that central line, to still surprisingly
>close  together, e.g., in the Brontopodus birdi (track-type name, not a
dino
>name, per se) tracks near Glen Rose, Texas.   [Yes, trackway evidence

I

late

>know some bikers are foolish, but, hopefully, not that foolish.]
